Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 32,254,321, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 32,254,321 | |
| -1 | -32,254,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,254,321.
Example:
1 x 32,254,321 = 32,254,321
and
-1 x -32,254,321 = 32,254,321
Notice both answers equal 32,254,321
With that explanation out of the way, let's continue. Next, we take the number 32,254,321 and divide it by 2:
32,254,321 ÷ 2 = 16,127,160.5
If the quotient is a whole number, then 2 and 16,127,160.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,254,321 | |
| -1 | -32,254,321 |
Now, we try dividing 32,254,321 by 3:
32,254,321 ÷ 3 = 10,751,440.3333
If the quotient is a whole number, then 3 and 10,751,440.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,254,321 | |
| -1 | -32,254,321 |
Let's try dividing by 4:
32,254,321 ÷ 4 = 8,063,580.25
If the quotient is a whole number, then 4 and 8,063,580.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,254,321 | |
| -1 | 32,254,321 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 137 | 187 | 1,259 | 1,507 | 2,329 | 13,849 | 21,403 | 25,619 | 172,483 | 235,433 | 1,897,313 | 2,932,211 | 32,254,321 |
| -1 | -11 | -17 | -137 | -187 | -1,259 | -1,507 | -2,329 | -13,849 | -21,403 | -25,619 | -172,483 | -235,433 | -1,897,313 | -2,932,211 | -32,254,321 |
